CVE-2023-52082Network attack vector

SQL injection via interpolated EXPLAIN query

Published Dec 28, 2023 · Updated Nov 27, 2024

SQL injection in Lychee 4.9.3 through 5.0.1 allows remote attackers to execute arbitrary SQL through database query bindings. The logSQL method substitutes binding values into a query string and passes that interpolated string to an unparameterized EXPLAIN statement. Exposure requires MySQL or MariaDB, both DB_LOG_SQL and DB_LOG_SQL_EXPLAIN enabled, and user interaction; default settings disable both flags.
